Both groups will receive shoulder treatment with an emphasis on 1) range of motion activities, 2) joint mobilization, 3) rotator cuff strengthening and 4) a home exercise program that consists of shoulder strengthening exercises. The active neck group will receive UPA's to the cervical spine; applied as 3 X 30 seconds, to each comparable (stiff or painful) segment. The physical therapist will place their hands on the neck of the patient for the placebo group but will not perform the oscillations that are characteristic of mobilization.
